Concrete implementation of LCWriter using SIO.
| void SIO::SIOReader::close | ( | ) | [virtual] |
| void SIO::SIOReader::getEvents | ( | EVENT::IntVec & | events | ) | [virtual] |
Return the run and event numbers of the events in the file - the file has to be open.
In case several input files are specified in the open() method - the run and event numbers of the events in the file that is currently open are returned. The size of the vector events will be twice the number of events, where i-th run number will be in events[2*i] and the i-th event number in events[2*i+].
Implements IO::LCReader.
References getNumberOfEvents(), and getNumberOfRuns().
| int SIO::SIOReader::getNumberOfEvents | ( | ) | [virtual] |
Return the number of events in the file - the file has to be open.
In case several input files are specified in the open() method - the number of events in the file that is currently open is returned.
Implements IO::LCReader.
Referenced by getEvents().
| int SIO::SIOReader::getNumberOfRuns | ( | ) | [virtual] |
Return the number of runs (run headers) in the file - the file has to be open.
In case several input files are specified in the open() method - the number of runs (run headers) in the file that is currently open is returned.
Implements IO::LCReader.
Referenced by getEvents(), and getRuns().
| void SIO::SIOReader::getRuns | ( | EVENT::IntVec & | runs | ) | [virtual] |
Return the run numbers of the runs (run headers) in the file - the file has to be open.
In case several input files are specified in the open() method - the run numbers of the runs (run headers) in the file that is currently open is returned.
Implements IO::LCReader.
References getNumberOfRuns().
| void SIO::SIOReader::open | ( | const std::string & | filename | ) | [virtual] |
Opens a file for reading (read-only).
| IOException |

References SIO::LCSIO::getValidSIOName().
| void SIO::SIOReader::open | ( | const std::vector< std::string > & | filenames | ) | [virtual] |
Opens a list of files for reading (read-only).
All subsequent read operations will operate on the list, i.e. if an EOF is encountered the next file in the list will be opened and read transparently to the user.
| IOException |
Implements IO::LCReader.
| EVENT::LCEvent * SIO::SIOReader::readEvent | ( | int | runNumber, | |
| int | evtNumber, | |||
| int | accessMode | |||
| ) | [virtual] |
Same as LCEvent* readEvent(int runNumber, int evtNumber allowing to set the access mode LCIO::READ_ONLY (default) or LCIO::Update.
| IOException |
Implements IO::LCReader.
References readNextEvent(), and readNextRunHeader().
| EVENT::LCEvent * SIO::SIOReader::readEvent | ( | int | runNumber, | |
| int | evtNumber | |||
| ) | [virtual] |
Reads the specified event from file.
Returns NULL if the specified event hasn't been found in the file.
| IOException |
Implements IO::LCReader.
| LCEvent * SIO::SIOReader::readNextEvent | ( | int | accessMode | ) | [virtual] |
Same as readNextRunHeader() but allows to set the access mode LCIO::READ_ONLY (default) or LCIO::Update.
| IOException |
Implements IO::LCReader.
| LCEvent * SIO::SIOReader::readNextEvent | ( | ) | [virtual] |
Reads the next event from the file.

| LCRunHeader * SIO::SIOReader::readNextRunHeader | ( | int | accessMode | ) | [virtual] |

| IOException |
Implements IO::LCReader.
| LCRunHeader * SIO::SIOReader::readNextRunHeader | ( | ) | [virtual] |
Reads the next run header from the file.
| IOException |

| EVENT::LCRunHeader * SIO::SIOReader::readRunHeader | ( | int | runNumber, | |
| int | accessMode | |||
| ) | [virtual] |
Same as LCEvent* readRunHeader(int runNumber) allowing to set the access mode LCIO::READ_ONLY (default) or LCIO::Update.
| IOException |
Implements IO::LCReader.
References readNextRunHeader().
| EVENT::LCRunHeader * SIO::SIOReader::readRunHeader | ( | int | runNumber | ) | [virtual] |
Reads the specified runHeader from file.
Returns NULL if the specified runHeader hasn't been found in the file.
| IOException |
Implements IO::LCReader.
| void SIO::SIOReader::readStream | ( | int | maxRecord | ) | [virtual] |
Reads maxRecord from the input stream and notifies registered listeners according to the object type found in the stream.
Throws EndOfException if less than maxRecord records are found in the stream.

Implements IO::LCReader.
| void SIO::SIOReader::setReadCollectionNames | ( | const std::vector< std::string > & | colnames | ) | [virtual] |
Limit the collection names that are going to be read to the subset given in the vector - all other collection will be ignored.
This might improve the reading performance considerably in cases where only a small subset of the collections in the event is needed.
Implements IO::LCReader.
| void SIO::SIOReader::skipNEvents | ( | int | n | ) | [virtual] |
Skips the next n events from the current position.
In fact simply reads the next n event headers so that the next event read is the (n+1)-th event.
Implements IO::LCReader.
